Article Synopsis
  • The mammalian pancreas has three key parts: exocrine acini and ducts, along with endocrine islets, all originating from a common progenitor during development.
  • Researchers created 18 human fetal pancreas organoid lines from samples between 8-17 weeks of gestation, with four lines showing the ability to produce all three cell types while thriving in culture for over two years.
  • Single-cell RNA sequencing revealed LGR5 cells as crucial developmental stem cells, indicating that these organoids are capable of long-term growth and can differentiate into acinar, ductal, and endocrine cells.

The purpose of an individual care plan in pediatric palliative care according to healthcare professionals: a qualitative study.

BMC Palliat Care

October 2024

University of Groningen, University Medical Center Groningen, Beatrix Children's Hospital, Hanzeplein 1, Groningen, 9713 GZ, The Netherlands.

Background: To ensure high-quality pediatric palliative care (PPC) and enable healthcare professionals (HCPs) to provide person-centered care for the individual child with a life-limiting or life-threatening illness and their family, the Individual Care Plan (ICP) for PPC was developed. However, in practice, the ICP for PPC is not used for all children in need of PPC. Insight into why, for which problem and for which children HCPs wish to use an ICP in PPC is therefore necessary to assure that the ICP can be fully implemented in practice.

Shared decision-making in pediatric palliative care in the Netherlands.

Curr Probl Pediatr Adolesc Health Care

January 2024

University of Groningen, University Medical Center Groningen, Beatrix Children's Hospital, Groningen, the Netherlands.

Shared decision-making (SDM) is a process in which health care professionals (HCPs) involve parents and children - when appropriate- to decide together on future treatment. These decisions are based on values that are important for the family, goals of care and preferences for future care and treatment. Elucidation of these values and preferences is preferably done early in the disease trajectory via so-called Advance Care Planning (ACP) conversations.

Agonist-controlled competition of RAR and VDR nuclear receptors for heterodimerization with RXR is manifested in their DNA binding.

J Biol Chem

February 2023

Department of Biophysics and Cell Biology, Faculty of Medicine, Doctoral School of Molecular Medicine, University of Debrecen, Debrecen, Hungary. Electronic address:

We found previously that nuclear receptors (NRs) compete for heterodimerization with their common partner, retinoid X receptor (RXR), in a ligand-dependent manner. To investigate potential competition in their DNA binding, we monitored the mobility of retinoic acid receptor (RAR) and vitamin D receptor (VDR) in live cells by fluorescence correlation spectroscopy. First, specific agonist treatment and RXR coexpression additively increased RAR DNA binding, while both agonist and RXR were required for increased VDR DNA binding, indicating weaker DNA binding of the VDR/RXR dimer.
